6sin(A)+3=4sin(A)+4

6 sin (A) + 3 = 4 sin (A) + 4

A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

Degrees

A = 3 0^{\circ} + 36 0^{\circ} n, A = 15 0^{\circ} + 36 0^{\circ} n

Solution steps

6 sin (A) + 3 = 4 sin (A) + 4

Solve by substitution

6 sin (A) + 3 = 4 sin (A) + 4

Let:

sin (A) = u

6 u + 3 = 4 u + 4

6 u + 3 = 4 u + 4 : u = \frac{1}{2}

6 u + 3 = 4 u + 4

Move

3

to the right side

6 u + 3 = 4 u + 4

Subtract

3

from both sides

6 u + 3 - 3 = 4 u + 4 - 3

Simplify

6 u = 4 u + 1

6 u = 4 u + 1

Move

4 u

to the left side

6 u = 4 u + 1

Subtract

4 u

from both sides

6 u - 4 u = 4 u + 1 - 4 u

Simplify

2 u = 1

2 u = 1

Divide both sides by

2

2 u = 1

Divide both sides by

2

\frac{2 u}{2} = \frac{1}{2}

Simplify

u = \frac{1}{2}

u = \frac{1}{2}

Substitute back

u = sin (A)

sin (A) = \frac{1}{2}

sin (A) = \frac{1}{2}

sin (A) = \frac{1}{2} : A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

sin (A) = \frac{1}{2}

A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

Combine all the solutions

A = \frac{π}{6} + 2 πn, A = \frac{5 π}{6} + 2 πn

a, - 10 = sin (a) + 15.2 cos (a)

0 = - 6 sin^{2} (θ) + 3 sin (θ) + 2

sin (2 x + \frac{3}{π}) = \frac{1}{2}

3 cot (\frac{x}{3}) + 1 = 0
